I make such an analogy, following my Pop!tech experience.

I would argue that barriers against ideas are to politics what barriers against trade are to economics. An import tariff on goods hurts both countries, but generally does the most damage to the country imposing the tariff. Similarly, when one side puts up barriers to listening to the other side's ideas, then both sides are damaged, with the side that refuses to listen suffering the worst.

Open systems win. The Angry Left, because it is closed-minded, is in no condition to govern. Barring a catastrophe at home or abroad, I doubt that it will be given the opportunity to do so.
